Official National Weather Service observations and Weather Underground data for LaGuardia Airport (KLGA)—the market's resolution source—confirm New York City's highest temperature on April 11 reached 60-61°F, driving trader consensus to 100% implied probability as preliminary readings finalized overnight. Breezy conditions under partly cloudy skies capped peak warmth amid a cool northerly flow, aligning with short-range forecast models from NOAA that projected highs in the low 60s despite earlier uncertainty from model spread. This outcome sits below the April climatological normal of 59°F at KLGA, reflecting transient weather patterns. Revisions to automated sensor data are possible but rare post-validation; final NWS climate reports expected within days could prompt minor adjustments if discrepancies emerge.
